IMPROVED STREET-SCRAPER.

, Speciiication forming part of Letters Patent No. 56,285, dated July10, 1866.

To all whom it may concern Be it known that I, MATHrAs SMITH, of Lake,in the county of Cook and State of Illinois, have invented a new anduseful Improvenient in Street-Scrapers; and I do hereby de clare andmake known that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings and theletters and gures marked thereon, which form part of this specification.

My invention consists in a novel apparatus, to be drawn by one or morehorses, whereby streets may be thoroughly scraped and cleaned and therefuse moved to any place, as desired, and there deposited in a simpleand easy manner, as hereinafter described, the operation of the saidapparatus being very effectual both as regards thoroughness in work andrapidity of execution.

To enable those skilled in the art to understand how to construct anduse my invention, l will proceed to describe the same withparticularity, making reference in so doing to the aforesaid drawings,in which- Figure l is a plan or top View of my invention 5 Fig. 2, aside elevation of the same, and Fig. 3 a vertical section thereof at theline x in Fig. 1.

Similar letters of reference in the several figures denote the sameparts of my invention.

A represents the wheels which support the machine, B being the axle, andC the thills, which latter, however, may be exchanged for a draft-poleor tongue if it should be desired to employ two draft-horses. Drepresents a front cross-bar, and E rear cross-bars, upon the saidthills, which rest upon and extend back of the axle, as shown, so thatthe machine is properly balanced by the driver or operator upon the seatS.

F G represent two vertical arms upon each thill or side of the machine,and extending down to the ground, or nearly so, K being braces to keepsaid arms securely in place.

Between the arms F, in suitable vertical grooves upon their interiorsides, is arranged an adjustable slide or scraper, H, extendingtransversely across the machine, having a vertical adjustment, its loweredge lying upon-the ground when in use, and being raised up, whendesired, by the driver by means of a lever, J, and connecting-rod I, asshown. To the lower end of the said arms F are pivoted the side boards,L, whose front ends moveV freely in su itable guides in the arms G, sothat said side boards lie edgewise upon the ground as the machine movesalong, notwithstanding any vertical or up and down motion ot' the frontend of the machine.

As the machine moves along the scraper H scrapes along allA the looseearth or other substances, the side boards, L, preventing the same fromescaping at the sides,.while the driver, at will, may raise up saidscraper, as aforesaid, and deposit the load wherever desired.

Having described the construction and operation of my'invention, I willnow specify what I claim and desire to secure by Letters Patent:

l. The combination ofthe adjustable scraper H, the guides F, and leverJ, arranged and operating substantially as and for the pulposes setforth. I,

2. In combination with the said adjustable scraper H, the employment ofthe adjustable side boards, L, arranged as and for the purposesdescribed. MATHIAS SMITH.
